With the Power Bank I have hassle free and fast
- To my notebook (Fujitsu)
with 16 Volt
- The battery of my smartphone
- The battery Bluetooth Speaker
- The evaporator of my battery (Kanger)
- To my Bluetooth receiver battery Speaker with USB iSmart safely charged and still 21 percent reserve. Would still be enough for a smart phone charging.
I find that class as flexible and powerful, this power bank.
On the way you have a little disadvantage. He is to wear uncomfortable in the pocket due to its high capacity = weight and size. Since you should have a shoulder bag or rucksack.
If the trip is better again shorter, fall back to a smaller brother of RAV- family.
The battery itself need to fully charge a good 10 to 11 hours.
I would recommend this product highly.
